The Scuti stars of the Cep--Her Complex. I: Pulsator fraction, rotation, asteroseismic large spacings, and the relation
Simon J. Murphy, Timothy R. Bedding, Anuj Gautam +2
We identify delta Scuti pulsators amongst members of the recently-discovered Cep--Her Complex using light curves from the Transiting Exoplanet Survey Satellite (TESS). We use Gaia…
Realistic Uncertainties for Fundamental Properties of Asteroseismic Red Giants and the Interplay Between Mixing Length, Metallicity and
Yaguang Li, Timothy R. Bedding, Daniel Huber +8
Asteroseismic modelling is a powerful way to derive stellar properties. However, the derived quantities are limited by built-in assumptions used in stellar models. This work presen…
Oscillation Frequencies of Moderately Rotating Delta Scuti Stars: Asymmetric Mode Splittings Due to Non-spherical Distortion
Zhao Guo, Timothy R. Bedding, A. A. Pamyatnykh +5
We find that the observed pressure-mode rotational splittings of slowly/moderately rotating Delta Scuti stars and Beta Cephei stars mostly have a positive asymmetry. That is, the l…
A New Catalog of 100,000 Variable \emph{TESS} A-F Stars Reveals a Correlation Between Scuti Pulsator Fraction and Stellar Rotation
Keyan Gootkin, Marc Hon, Daniel Huber +3
δ Scuti variables are found at the intersection of the classical instability strip and the main sequence on the Hertzsprung-Russell diagram. With space-based photometry providing m…
The Hybrid Debris Disk Host Star HD 21997 is a High-Frequency Delta Scuti Pulsator
Aldo G. Sepulveda, Timothy R. Bedding, Simon J. Murphy +3
HD 21997 is host to a prototypical "hybrid" debris disk characterized by debris disk-like dust properties and a CO gas mass comparable to a protoplanetary disk. We use Transiting E…
Low-amplitude solar-like oscillations in the K5 V star Indi A
Mia S. Lundkvist, Hans Kjeldsen, Timothy R. Bedding +17
We have detected solar-like oscillations in the mid K-dwarf Indi A, making it the coolest dwarf to have measured oscillations. The star is noteworthy for harboring a…
